Ok so i need some help I built my system, its got a p4 3.4 in there, 1gb ram, etc. My buddy built a new comp about 6 months ago and went to a PCI Express system so he gave me his AGP ATI x1600, was a good video card, better than the Geforce 6600 I had, so i put it in. Now ive had it in for 6 months and no problems. Recently, while playing World of Warcraft (on semi conservative settings) the game will put the monitor into standby, the keyboard locks (meaning the numlock and caps lock keys dont change the lights) and then sits there. I can still hear the audio playing, and the computer stays on. The only thing to do is manually restart the system. Now normally this occurs after the computer has been on for a while, and after it happens, if i turn the computer off, then back on again it will be fine the rest of the night. I was thinking it was a heat issue, but simply turnin the power back on and off wouldnt work as the card or mobo wouldnt cool that fast. I was then thinking maybe a power issue. The card takes a seperate plug like that used to hookup a floppy drive or a fan, so I isolated that power cable so the video card is the only thing on there. Still did it. So at this point I dont have any ideas. I thought the mobo might be going bad or soemthing, but I put my 6600 back in and it works fine. and has for the last 2 days. I really like the x1600 and dont want to just trash the card but Im thinking it might be going out. Any other ideas?
